ELECTRIC TELPHERAGEYAPPARATUS.

SPECIFICATION forming part of Letters Patent No. 471,790, dated March29, 1892.

Application filed December 29, 1890; Serial No. 376,134. (No model.)

To all whom it may concern.-

Be it known that I, MIDBURY W. HASSAN, of Rochester, in the county ofMonroe and State of New York, have invented a certain new and usefulImprovement in Electrical Apparatus for the Rapid Transit of Packages;and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the drawingsaccompanying this specification.

My improvement relates to electrical apparatus for the rapid transit ofsmall packages such as mail-matter and other articles; and it consistsof an overhead system composed of wires attached to supporting-poles,one of said wires, which is the working conductor, being spirallygrooved or threaded, and a pointed car running thereon, provided with atrolley that engages with the ground-wire to complete the circuit.

It also comprehends a peculiar arrangement of inclined ways, whereby thecar is enabled to pass the supporting-pulleys, all as hereinafterdescribed.

In the drawings, Figure 1 is aside elevation, partially in section, ofmy improvement. Fig. 2 is an enlarged cross-section of the car. Fig. 3is a front elevation of one set of the inclined Ways for guiding the carover the supportingpulleys. Fig. 4 is a longitudinal section of the car.

A indicates one of the supporting-poles on which the wires are strung.

'B is the working wire, and O the return or ground wire, arranged oneabove the other, or horizontally, if desired. The Working con-- ductor Bis of any suitable diameter and is provided with spiral threads orgrooves a a, as shown. A single thread may be used effectively; butpreferably two or more are used, similar to the double threads of ascrew. This wire is supported at intervals by insulated pulleys b 6,over which the wire passes freely, the pulleys being grooved to receivethe wire. The ground-wire O is supported by hangers c 0, located aboveit, by which means the trolley can run free.

D is the car or conveyer, the same consisting of a hollow cylinder withpointed ends, the latter facilitating the rapid passage of the car andalso furnishing an inclined surface that enables the car to pass readilyup over the inclined ways. The ends of the car are tubular and passloosely over the wire.

E is the armature within the car, resting between head blocks f f, and GG the fieldmagnets. The armature is also cylindrical, and at one end ithas keys or splines d d, which fit in the spiral grooves a, aof theworking wire 13. By this means when the arma- 6o ture revolves the keysrun along in the spiral grooves and impart forward motion to the car.The field-magnetsG Gare of segmental form and are located in the bottomof the car, thereby adding weight that tends to keep the car fromturning. This result, however, is principally effected by thetrolleyhereiuafter described.

H H are inclined ways located at each supporting-pole to enable the carto pass over the pulleys. The ways consist of inclined arms that pointin the opposite direction to that in which the car runs, and they are sofar separated as to catch the pointed end of the car and guide it upover the pulley, lifting the wire with it. The wire then drops back intoplace on the grooved pulley. In case cars are to be run in bothdirections, these ways are made double, pointing in opposite directions.v I is a trolley-arm of ordinary construction attached to the top of thecar and running in contact with the ground-wire C. By this means thecurrent is maintained by which motion is imparted to the car, and,furthermore, it keeps the car in an upright position and prevents itfrom turning. The end of the trolley that engages with the ground-wireis provided with guards to preserve contact.

By means well known a resistance may be '90 produced to the car near thecrossing of the pulley o and at stations, thus making the operationentirely automatic.

The car may be made of sufficient capacity to carry the articles to betransported or it 5 may be used as a motor to draw another receptaclewhich carries the articles.

The circuit is made by means of the conducting-wires g h '5 and theordinary brushes k k and commutator Z. The current passes from theconducting-wire through the armature, thence through wire 9 to one ofthe brushes, thence through the commutator and the other brush, thencethrough wire hto the 2. The combination, with the wire B and pointedcar, D, of'the pulley Z supporting the 1 wire, and the inclined ways H Hfor guiding the car over the pulley, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing 20 witnesses.
